Progressive/Multifocal lenses include three fields of vision, without lines. In a progressive the top portion of the lens is a distance prescription. This funnels down through an intermediate range prescription to a lower portion used for near vision eg reading. Free Form progressives are the latest technology and offer a lens with less peripheral distortion in all vision fields. Spex Appeal® frames are fitted with Digi Pro Free Form lenses and include a hard coating to reduce scratching plus UV protection and anti-reflection. If this is the first time you are ordering progressive lenses be aware some people need time to adjust to wearing them. However once you adjust you’ll no longer need to change glasses for each application.
